Find array value

Question

My array:

var PrivateChatList = [];

And push key and value (just example):

PrivateChatList['supporter1'] = 'player1';
PrivateChatList['supporter2'] = 'player2';
PrivateChatList['supporter3'] = 'player3';
PrivateChatList['supporter4'] = 'player4';
PrivateChatList['supporter5'] = 'player5';
PrivateChatList['supporter6'] = 'player6';
PrivateChatList['supporter7'] = 'player7';

I want to find "player4" key on function. How can i find ?

• Andy: That's an object, not an array.

Answer 1

function getObjectKeyFromValue(object, value)
{
 for(var k in object)
 {
 if(object[k] == value)
 {
 return k;
 }
 }
 return '';
}
var key = getObjectKeyFromValue(PrivateChatList, 'player4')
alert(key); // 'supporter4'
